Sometimes when my mom stops by I’ll have her give me a hand with something animal related. She has owned horses before, likes to love on my various farm critters, and likes to be needed.
I asked her to hold the horse while I dewormed him and the donkeys.
My horse has been very good for taking the various pastes, so after I deposited the ivermectin paste on the back of his tongue and held his head up for a minute, I let her the do the “Swallow… swallow...…wadda good widdle poneh woneh you are. Ummy good medicine, swallow it all up. Mmmm, now wasn’t that tasty?“ bit.
I told her to watch to be sure he didn’t spit any out while I tackled the donkeys. Well, she musta had a senior moment and paid no attention to that while she started grooming him. After I came back over from doing the donkeys there was some wormer on the ground. Both had the same look on their face too… “Gee, I have no idea how that got there.”
He had stepped in it and I really couldn’t judge how much it was.
In ruminants it is generally safe to repeat an ivermectin dose injection right away if there is a goof up since it isn’t being given orally and is a safe drug. However, I didn’t have another tube at the moment and I also paused to consider that the paste goes directly into the digestive system.
I did have a tube of Exodus (different class) but didn’t think that was right incase he did indeed get some of the ivermectin down.
So, my question is …. When the horse spits out ivermectin paste and you can‘t tell how much he did/didn’t get, how soon can another dose of ivermectin paste be given. Is it safe to repeat right away when it happens?
Or, should one give a full dose of another drug class, although that doesn’t seem the correct logic to me.
Just for reference, what about the other drug class dewormer pastes?
